9 Claims. (Cl. 216-20) This invention relates to a binding tape applicator and more particularly to a device for applying a binding tape along the cut edge of a carpet backing.

It is an object of the invention to provide a device which is of simple construction and which may be manipulated in a simple manner to apply a binding tape along the edge of carpeting, adhesive material being applied to the tape or to the carpet backing so that the tape applied by the device will adhere firmly to the carpet backing without stitching.

More specifically, the invention contemplates I a device which is constructed to apply a binding tape to a carpet backing such that the tape along one of its edge portions is rolled upwardly around the cut edge of the backing material with the extreme edge of the tape imbedded in and lying along the line between the carpet backing and pile. The device is constructed such that the binding tape applied thereby prevents unravelling of the backing or pile of the carpet and at the same time presents a neat appearance along the edge of the rug.

Other objects in the way of improvements in the construction of the device and its operation will become apparent from the following specification and drawings in which:

Figure 1 is a side elevation of the device partly in section.

Figure 2 is a bottom view of the device.

Figure 3 is a partial perspective view of the bottom and rear end of the device with the tape removed.

Figure 4 is a sectional view taken along the line 4-4 in Figure 1.

Figure 5 is a sectional view taken along the line 5-5 in Figure 1 and showing the manner in which the tape is held in position on the bottom guide plate when the device is ready for use.

Figure 6 is a view corresponding to Figure 5 showing the manner in which the binding tape is applied along the edge of a carpet backing.

Referring to the drawings, and particularly to Figure 1, the tape applicator of this invention is shown comprising a base member [0 having a pair of upright arms [2 at the forward end thereof between which is supported a roll H! of binding tape l5. Arms IZ'are mounted on base III by means of screws l6 and are provided at their upper ends with a plurality of vertically spaced and horizontally aligned apertures l8 for accommodating rolls of binding tape of different sizes. The binding tape is preferably wound on a spool 20 which is supported between arms l2 by means of a pin 22 which is arranged to extend through a corresponding pair of the apertures l8. Base 10 is preferably of rectangular shape and is horizontally slotted transversely through its mid portion as at 24 so that the upper portion of 'the base serves as a handle 26 for the device. The front face of base I0 is vertically slotted so as to provide a recessed guide 28 for guiding the tape from roll [4 downwardly and along the bottom face 30 of base I0. At its lower end guide 28 is fashioned with a rounded corner 32 around which the tape is pulled when the "device is manipulated along the edge of a carpet.

' On the bottom face 30 of base I0 there is mounted a shoe or guide plate 34. Plate 34 is ar- 7 ranged to be adjustably fixed on base I!) by means .of screws 36 which extend through transverse slots 38 in plate 34 and thread into base [0. Slots 38 allow for the shifting of plate 34 in a transverse direction so as to accommodate the device for tapes of difierent widths. Plate 34 is mounted on face 30 so that the exposed face 40 of the plate is spaced below the bottom face of base 10 and'so that the front edge 42 of the plate extends transversely of the tape and is spaced rearwardly of the rounded corner portion 32 of guide 28. Along one edge plate 34 is bent downwardly to provide a depending flange 44. At its front end flange 44 is bent outwardly as at 48. The mid portion 50 of flange 44 extends downwardly substantially perpendicular to the face 40 of plate 34. In effect,

flange 40 forms an angle of over 90 at the front of plate 34 which gradually increases to 90 at the portion 50 and which then turns gradually 'inwardly to an angle of less than 90 at the portion 48. Flange 44 is shaped in this manner so as to roll or fold the tape around the cut edge '52 of a 'carpet backing 54. The perpendicular flange portion 50 extends along a substantial portion of-the plate and serves as a guide when the device is pushed'along the edge of a carpet.

For the purpose of temporarily holding tape IS in position on plate 34 a spring 56 is provided. Spring 56 is fashioned'with a short arm 58 which is adapted to be inserted within an aperture on the rear face'of base Ill and with a relatively long arm 60 which, when arm 58 is engaged with-base H], is adapted to extend along and yieldably enfrom roll l4. Accordingly, mounted as by screws 64 across the front end of base l so as to span guide recess 28. Bracket 62 supports a container 55 the side edges of which are shaped to provide supports for an adhesive 5 applicator roll 68. Container 66 is arranged such that the outer surface of tape l5 contacts the cylindrical surface of roller 68 and causes the roller to rotate and idip in the bath: of: adhesive a bracket 62 is within the container. The adhesive employed 10 "localized portion of the tape'so that in efiect the is preferably aqueous dispersion of latex. Roller 68 also serves to guide the tape l5 downwardly into guide portion 28 in the front face ofbase i ll.

When it is desired to employ the device for pressure applied to the handle portion 26 is sub- "stantially entirely utilized for the purpose of 'vpressing'nthe tape against the carpet backing.

We have also found that the provision of the applying a binding tape to a carpet'backing;*the *"recessed giiide -ifl at the front end of the base roll of tape is arranged between arms I 2 as shown in Figure 1 and a portion of the tapez-isrunwound from roll I and threaded over roller 68 downwardly through guide 28 and along plate34 with the edge of the tape substantially aligned with -the rear face'pf base' i ll :and'springin the other "together with the curved corner portion 32 -legfifl 'from the' do'tted line position shown in' ing a oll-of'biriding tape above'the-base;"said Figu-re Z *to the*-'-positionshown -in -solid lines -wh'ere' 'it re's'iliently engages the tape-and holds 'the edge portion thereof against the inner face of flange 44 along -the l inwardly bent portion '48 :of the' flange.

The device is then pushed forwardly-along the edge of the carpet-"while a downward pressure is' exerted. Since the tape adheres to the carpet ba'cking it is 'cbvious that" as base i 0 '-is-pushed -base at its fronterid having aguide' member exztending downwardly and in=an= arcua-teypathto e. sald bottom faceand a substantially flat plate member on-said bottom face extending'lcngitudinal-ly 'of saidbase and-havingits"lower' face spaced below the plane pfthe *bottom .faceof said base, said plate being=mounted-on"saidfbase -with-*its" front'edge spaced rearwardlyfromfsaid =guide means and having a depending flange'a'long *a longitudinal edge thereofxsaid "flangeforming "an" obtuse angle *withithe plate. at the. forward end thereof and an acute angleiat' the rear end 'thereof and having a depth 1 corresponding? to 'the'thickness ofsaid carpet backing, the portion ofqsaid flange between'said ends being straight and of substantial length .and depending perpenidicular ly' from said base.
